Why is Heechul indifferent to being shorter than the members of KNK?

KNKappeared exclusively on the June 22 airing ofMBC Everyone's 'Weekly Idol'!

The group is comprised of really tall members, the tallest at 189 cm (~ 6'2") and the shortest at 180 cm (~ 5'11") and an average of 185 cm (~ 6'1").  Heechulstood in the middle, which caused immense laughter, especially byHanias you can see in the screenshot below.

She then consoled him with,"Still, you're good looking,"and he replied,"I don't lose out in looks no matter where I go," causing even more laughter.

Tallest memberSeungjunthen said,"I drank the earthworm juice my grandmother gave me when I was young to grow up." Worth... it...?
